VENDING. MACHINE.

Application filed April 11,

This invention relates to improvements in vending machines and hasparticular reference to a machine for vending newspapers, magazines andthe like periodicals.

The principal object of the invention is to provide means whereby asingle newspaper or magazine may be delivered to a customer who places acoin in the coin controlled mechanism of the device.

Another object is to produce a device which is positive in itsoperation.

Another object is to produce a device which is simple in constructionand therefore one whereln the article being dispensed will not becomejammed. 4

A further object is to'provide means Whereby pilfering of the dispensingdevice will be impossible.

A still further object is to provide means whereby various coinarrangements may be effected so that periodicals of different values maybe dispensed.

Other objects and advantages Wlll be apparent during the course of'thefollowing description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a front elevation of two of my devipes placed one above theother,

Figure 2 is an end elevation of Figure 1 on a reduced scale,

Figure 3 is an enlarged detail cross section of my device,

Figure 4 is an end elevation partly broken away in order to disclose thecoin mechanism,

Figure 5 is an enlarged fragmentary detail view of the coin mechanism,

Figure 6 is an enlarged'fragmentary detail view showing the manner ofdispensing,

F i ure 7 is a fragmentary detail view showing t e means for closing thecoin controlled slot, and

Figure 8 is an enlarged fragmentary detail view showing the slot closingmeans in front elevation.

In employing my device it is proposed to superimpose a num er of thedevices in vertical alignment and to insert in each separate device newsapers or the like periodicals, each device olding a particularnewspaper.

The device consists essentially of a rectangular box-sh aped structurethe back of which is indicated by the numera 5 and the bottom 1928.Serial No. 269,184.

by the numeral 6. A glass plate 7 forms the front of the box likestructure behind which 18 a space 8 in which a newspaper may bedisplayed. A sliding plate 9 is supported in grooves 11 carried in theend walls 13 of the box-like structure. This plate 9 is adjustablysupported by adjusting screws 12 one of which is located at each end ofthe p-late and are adapted to contact brackets 14 mounted upon the endsof the walls 13. This plate 12 has a hinged member 16 pivoted as at 17to the lower edge thereof.

An arm 18 is rigidly secured to the member 16 and is in turn pivoted toa link 19 which is pivoted as at 21 to the dispensing slide 22, whichrests upon the bottom 6. This slide 22 is adapted to be projectedthrough an opening 23 formed belowthe glass plate 7 and protected by arain shield 24. I

In order to. actuate the dispensing plate 22 I provide a shaft 26 whichprojects from end to end of the device at a point below the bottom 6.This shaft carries plates 27 and 28 at its respective ends. These platesare immovably secured to the shaft 26. The plate 27 is connected by alink 29 to a plate 31 which plate is in turn connected 'by a pin 32 tothe dispensing plate 22.

It is noted from Figure 3 and Figure 6 that the rear edge of thisdispensing plate is curved upwardly as shown at 33 and the for- Ward endis curved upwardly as shown at 34, the purpose of which will be laterseen. The plate 28 has pivotly connected thereto a link 36 which is inturn connected to a plate 37 which plate carries a pin 38 connected tothe dispensing plate 22 but at the opposite side from the pin 32. Thesepins 32 and 38 each slide in slots 39 formed in the end walls 13. Inorder to retract the dispensing plate 22 I provide springs 41 and 42which have one end connected to the end walls 13 and have their oppositeendsconnected to the plates 27 and 28 respectively. An operating leveris shown at 43 which operating lever carries a haridle 44.

The operation of the structure thus far described is as follows A pileof articles to be dispensed such as newspapers is placed within thebox-like container so as to lie u on the dispensing plate 22 asillustrated in l igure 6. Assuming that the coin controlled mechanismhas been operated so as to release the dispensing mecha-, nism, then bypulling forwardly upon the handle 44 motion will be transmitted to theshaft 26 and the plates 27 and 28. This will transmit motion through thelinks 29 and 36 to the; dispensing plate 22 which will cause the plateto move forwardly. As soon as this plate commences to move, the links 19and thelever 17 will act to cause the curved member 16 to lift upwardlyas illustrated in Figure 6. This upward movement will support the frontedge of the pile of papers permitting only the lowermost paper to passtherebe neath.

In order to accommodate for the various thicknesses of various papers,the plate 9 may be raised or lowered by means of the screws 12 therebycontrolling the lowermost point of the swing of the curved member 16. Bycurving the rear portion of the dispensin plate upwardly-as at 33, Icause the rear en to compress the issue being dispensed thereby givingthe issue greater rigidit and thus forcing the same to slide evenlybeneath the pile of superimposed papers without the customary bucklingeffect which would otherwise occur.

As soon as the paper has been moved through the opening 23 it is graspedby the purchaser and pulled from the device. The springs 41 and 42 nowfunction to return the parts to their normal position. In order toaccomplish the operation just described, it is first necessary to unlockthe controlling mechanism through the depositing of a coin in the coinopening 46, which coin will move into a coin chute 47 where it will comeinto contact with the nose 48 of a locking lever 49, which locking leveris pivoted as at 51 to one of the end pieces 13 and is held inengagementwith the coin chute by a spring 52. This locking lever carries a lockingpaul 53 which is pivoted thereto as shown at 54 and has ratchet teeth 56and 57 formed thereon. Theseratchet teeth are adapted to engage ratchets58 and 59 respectively formed upon a plunger rod 61. This plunger rodhas an offset head carrying a pusher 62 (see Figure 5) and is pivoted atits lower extremity as shown at 63 to a pull rod 64, which pull rod isadjustably secured as shown at 66 to the plate 28.

In order to prevent the depositing of coins in the coin opening 46,after the last paper is dispensed I provide a lever 67 which is pivotedas at 68 to the bottom 6. One end of this lever extends upwardly throughthe bottom 6 and the tray 22 as shown at 69 (see Figures 7 and 8.) Thefront end of this lever is slidabl held in a slot 71 formed in the leg72 of an -shaped member 7 3.which is pivoted as at 74 to the front plateof the cabinet which carries the glass plate 7. The upper end of thisL-shaped member is normally out of alignment with the opening 46 throughthe fact that the weight of the papers within the device rests upon theend 69 of the lever 67 but as soon as the last paper has been removed,this end 69 will project upwardly through the opening thus permittingthe opening 46 to be closed by the upward extremity of the L- shapedmember .7 3. In order to make this action more positive a counter weight76 may be employed if desired.

Referring now to Figure 4 it will be noted that the locking pawl 53 hasa semi-circular opening 77 formed therethrou gh. This permits of apivoted key78 passing therethrough, which key is pivoted as at 79 to thelocking lever 49. The result is that when this key 78 is in positionshown in this figure the ratchet 56 will underlie the ratchet tooth 58.-When the key is moved through an arc of one hundred and eighty degrees,the locking pawl will be moved to the dotted line position of thisfigure, with the result that the ratchet 57 will underlie the tooth 59and at the sameti ne the locking lever 49 will be moved a slightdistance rearwardly. The result is that when the device is in the fullline position of this figure, if a dime is deposited and the mechanismactuated the dime will be of sufieient diameter to engage the nose ofthe member 48 so thatwhen the pusher 62 moves downwardly the lockinglever 49 will be moved rearwardly against the tension of the spring 52thus withdrawing the ratchet 56 from beneath the ratchet tooth 58.

When the locking pawl is in the dotted line position of this figure anda nickel is deposited, then the same will be of suflicient diameter tostill engage the member 48 and cause the actuation as above described.When it is desired to use several coins as for instance, a three'centpaper, the member 48 is moved to the dotted line position of Figure 5with theresult that it is then necessary to insert three coins beforethe plunger 62 will cause the unlocking action before it is depressed.

It will thus be seen that I have produced a device wherein coins ofdifferent dimensions may be employed for actuating the releasemechanism, and further I have provided means for dispensing papers orthe like, one at a time without the same being mutilated. It is to beunderstood that the form of my invention herewith shown and described isto be taken as a preferred example of the same and that various changesrelative to the material, size, shape and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

Having thus described my invention, I claim i 1.' In a device of thecharacter described,

and to said dispensing plate, means for rotating said shaft, saiddispensing plate having upturned ends and a curved member positionedabove said dispensingplate and spaced therefrom, said plate beingadapted to' overlie the article to be dispensed and to support theforward edge of the article superimposed upon the article beingdispensed.

2. In a device of the character described, a box-like structure. a.slidable dispensing plate positioned in said box-like structure, a shafttransversely positioned beneath said box-like v structure, platescarried on the ends of said shaft, links connected to said plates and tosaid dispensing plate, means for rotating said shaft, said dispensingplate having upturned ends and a curved member positioned above saiddispensing plate and spaced therefrom, said plate being adapted tooverlie the article to be dispensed and to support the forward edge ofthe article superimposed upon the article being dispensed, and means foradj usting said curved member to or away from said dispensing plate.

In testimony whereof I aflix my signature. v
